【摘要】：本文的目标是设计一款具有自主知识产权的多功能连铸机辊缝测量仪。在设计中采用DSP芯片TMS320F28335作为辊缝仪测量系统的处理器，以DSP为核心单元设计外围硬件电路，在uC/OS-II嵌入式实时操作系统平台上完成多功能辊缝测量仪的软件设计，并利用上位机软件来分析显示测量数据，数据的传输是采用无线的方式实现的。整个系统设计实现了对连铸机物理参数的测量，通过传感器采集连铸机的辊缝值、角度值、导辊旋转情况、喷嘴喷雾情况等数据，将这些数据进行初步处理后存储起来，然后通过无线传输的方式送给上位机，在上位机软件中再次分析处理后以图表的方式显示出来。连铸机维护人员根据显示出来的最终结果，判断出当前被测连铸机的工况。文中介绍了连铸机各个物理参数的测量原理以及系统整体的软硬件设计方案。硬件设计方案是以DSP为处理器，采用内外部ADC为模数转换单元，搭载信号调理、电平转换、显示、通讯、电源等模块电路共同组成了辊缝仪测量硬件平台，分析了各硬件模块电路的功能，并验证硬件电路的可行性；软件设计是硬件为基础，采用嵌入式系统的方式实现，通过在CCS开发环境中完成了uC/OS-II操作系统的移植工作，采用多任务处理功能实现系统的软件编程；系统软件设计完成之后，结合软硬件测试整个系统功能就显得很必要，，整个设计的完成需经过了多次测试，前期主要是实验室测试，并给出一些具体的测试方法，通过实验室测试之后才能进行现场测试；上位机软件主要用来显示测量结果，文中给出了一些测量结果的显示方式，并简略说明如何分析这些显示出来的数据。最后，总结论文的主要工作及其存在的问题，并对未来工作提出了建议和改进的方向，对于辊缝仪的发展也做出了一些探讨。经论证本文设计的多功能辊缝仪设计合理、检测准确、工作稳定、操作简单，具有很高的应用价值。
[Abstract]:The goal of this paper is to design a multi-function continuous casting machine roll gap measuring instrument with independent intellectual property. In the design, DSP chip TMS320F28335 is used as the processor of the roll gap measuring system, and the peripheral hardware circuit is designed with DSP as the core unit. The software design of the multifunction roll gap measuring instrument is completed on the uC/OS-II embedded real-time operating system platform. The data of display and display are analyzed by the software of upper computer, and the data transmission is realized by wireless way. The whole system is designed to measure the physical parameters of continuous casting machine. The data of roll gap value, angle value, guide roll rotation, nozzle spray and so on are collected by sensor, and these data are stored after preliminary processing. Then it is sent to the host computer by wireless transmission, and then analyzed and processed again in the software of the host computer, and then displayed in the form of chart. The maintainers of the caster judge the current condition of the CCM according to the final result. This paper introduces the measuring principle of each physical parameter of the continuous casting machine and the whole software and hardware design scheme of the system. The hardware design is based on DSP processor and internal and external ADC as A / D conversion unit. The hardware platform is composed of signal conditioning, level conversion, display, communication, power supply and other modules. The function of each hardware module circuit is analyzed, and the feasibility of the hardware circuit is verified. The software design is based on hardware and is implemented by embedded system. The transplant of uC/OS-II operating system is accomplished in CCS development environment. After the software design of the system is completed, it is necessary to test the whole system function with the software and hardware. The completion of the whole design has to go through many tests, mainly laboratory tests in the early stage. Some specific test methods are also given, which can only be tested in the field after the laboratory test. The host computer software is mainly used to display the measurement results, and some display methods of the measurement results are given in this paper. And briefly explain how to analyze these displayed data. Finally, the paper summarizes the main work and its existing problems, and puts forward some suggestions and improvement directions for future work, and also makes some discussions on the development of the roll gap meter. It is proved that the multifunctional roll gap meter designed in this paper is reasonable in design, accurate in detection, stable in work, simple in operation, and of high application value.
